A trait that increases reproductive success produced by natural selection in the context of a particular environment.

• A. Adaptation
• B. Culture
• C. Primate
• D. Evolution

Answer: (A)

An adaptation is a heritable trait that increases an organism’s reproductive success in a given environment, arising through natural selection as populations respond to environmental pressures. It can be anatomical, behavioral, or physiological and is shaped to work well in the specific conditions the organism faces. For example, a beak shape that allows more efficient feeding in a particular food source or a pigment pattern that helps hide an organism from predators can be adaptations to that environment.

Culture refers to learned behaviors and practices that can influence reproduction but are not necessarily inherited genetically as traits produced by natural selection. Primate is simply a taxonomic group, not a trait. Evolution is the overall process of change in populations over time, not a specific trait itself. Thus, the described trait is an adaptation.
